ATTORNEYS Patented May 26, 1953 BOX Benjamin L. Thurston, Pawtucket, R. I., assignor to Frost Box 00., Inc., a corporation of Rhode Island Application November 20, 1951, Serial No. 257,319

1 Claim. I (Cl. 229-14) This invention relates to a box of the typ where the cover section telescopes over the body section of the box.

Heretofore in boxes of the above mentioned character a lip has frequently been provided by extending the bottom wall of the box out beyond the side and end walls so that a cover which telescopes the side and end walls of the body section will engage the lip and be limited in its telescoping movement. In some cases it is desirable t omit the lip, and in such cases difficulty is encountered if the thickness of a piece of stock is utilized in the cover section for engagement with the upper edge of the walls of the body section of the box.

One of the objects of this invention is to provide an arrangement so that the cover section of the box is definitely limited in the amount that it may slide on to the body section without the use of a lip in the bottom of the box.

Another object of the invention is to provide a limiting means which will be entirely hidden from view when the cover is in position on the box.

Another object of the invention is to provide a limiting means which may be varied so that the amount of telescoping of the body and cover sections may be predetermined.

With these and other objects in View, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings:

Figure 1 is a perspective View illustrating a cover section lifted from the body section of the box to expose the limiting means within;

Figure 2 is a sectional view substantially through the center of the box as indicated on line 2-2 of Figure 1;

Figure 3 is a similar section of a fragmental portion of the box which illustrates the cover and box sections as in closed position;

Figure 4 is a bottom plan view of the cover section of the box;

Figure 5 is a perspective view of the liner.

In proceeding with this invention, I provide a liner for the cover of the box which extends along the inner surface of the side and end walls of the cover and is of a depth less than these walls. This liner, instead of going into each of the corners, is arranged at an angle to the adjacent side and end walls at the corner to bridge the corner, which provides an edge to engage the upper edge at the corners of the body of the box to provide a good support so as to limit the telescoping action of the cover on the body, and in 2 order to space the angular portions at the corners and more accurately position the liner in place, tabs extend along the top wall of the box into each of the corners, which provides a means for securing the liner in position and for p V i shifting thereof.

With reference to the drawings Ill designates the body section and II the cover section of the box, while I2 (Fig. 5) designates the liner. The body section of the box comprises a bottom wall I4 with side walls I5 and I6 and end walls I! and I3 extending upwardly at right angles thereto and providing a surrounding enclosure. The cover section of the box is similar but in inverted relation, having a top wall I9 with downwardly extending side walls 20 and 2| and end walls 22 and 23 extending at right angles to the top wall and providing a surrounding enclosure. These two sections I0 and I I may telescope together as shown in Figure 3, and in order to limit this telescoping action, I provide the liner as shown in Figure 5, which comprises side wall portions 24 and 25 and end wall portions 26 and 21 to extend respectively along these walls of the cover. However, these portions do not extend the full length of the side and end walls but rather stop short of the corners. Abutment portions 28, 29, 30, 3 I, and 32 bridge the corners at an angle to the adjacent side and end walls at each corner, which angular relation is substantially 45. In order to support this liner in position, tabs 33 extend from the angularly arranged abutment portions at each corner and are of a size to extend into the corner with their edges 34 and 35 engaging the adjacent side and end walls, while their face portions 36 are in face-toface relation with the inner surface of the top wall I9 and may be cemented to the top wall at these locations so as to hold the liner in position.

The liner may be formed of one single piece of strip material with the abutment portions 3| and 32 interlocked by reason of a recess 31 in the portion 3| to extend over the junction of the portion 32 with the wall 25 and be locked into position. By this arrangement the liner portions 28, 29, 30, 3|, and 32 will engage across the corners of the walls I5I8 as shown in Figure 3 and prevent the cover from telescoping on to the box a distance beyond a predetermined selected amount which is calculated as the difference in the width 8f the liner and the height of the top wall of the I claim:

A box comprising a body section having a bottom wall and a cover section having a top wall,

each section being rectangular with side and end Walls, the side and end walls of the cover section telescoping over the side and end walls of the bo y section when in closed position, and a liner strip of a depth less than the depth of the side and end walls of the cover section extending along the inner surface of the side and end walls intermediate their ends with one edge engaging thetop wall and the other edge abutting the edge of the side and end walls of the body section, said liner strip having a corner bridging portion extending at an angle to the walls for bridging the corners and limiting the telescoping of the sections one over the other, the corner bridging portions of the liner having tabs extending along the top wall and abutting the adjacent side and end Walls BENJAIVIIN L.
